Update 01.28.17: Weekend Work
DINAN is having sale on software for E53 so I jumped on it. Not many times DINAN is 50% off anything. Another reason being; my transmission has the harsh 2-1 downshift at normal operating temp. Only time it is not there is prior to normal operating temp, and sport mode. Adding the DINAN Automatic Transmission software couldn't hurt. For $280 for transmission and engine software was a no-brainer for me. The shop didn't even charge me labor and hooked me up with a DINAN t-shirt. I also snagged some old DINAN brochures because I thought they were cool.
StephenVA was nice enough to let me swing by his house today and wrench on my vehicle. Super knowledgeable and has all the tools. Thanks again! About half the plugs were covered in oil, the other half were just old. Really surprised I wasn't having misfires in cylinder #4 & #8 because those were the worst ones. Fresh NGK Iridium plugs and Bremi coils in. Still need to replace the valve cover gaskets, that'll be next. Beast started right up, idled much better (rough idle is gone), misfires are gone now. Did an oil service as well when I got home. Previous owner had a Hengst oil filter in there
. Fresh Mobil1 0w-40 and Mann Filter.
